Question

A boy runs faster than a girl .How will you prove this statement ? What phisical quantities do you require to answer this question?

Answer 1

To prove that a boy runs faster than a girl,we need to do the following thing -

• At first in the normal conditions for both the boy and the girl,we need to precisely measure their running speed by different preferable methods.

• Then we have to compare the measurements of the speed of both boy and girl.

If the speed of boy becomes greater than the speed of girl,we can easily prove that the boy runs faster than the girl.

- Physical quantities are such quantities which we can easily measure.

In this case we need the physical quantities of their running speed,to prove who is faster.

Answer 2

Explanation:

• For the particular age and built of a boy and a girl, the boy is seen to be running faster for which the physical quantities can be measured.
• The physical quantities that we can see, when both the genders are running together, the speed of boy and girl determined by the built of the body and the weight of them.
• It is seen that girls require lesser amount of calories while boys have more amount of calorie intake which provides better muscle strength.
• And when muscle strength is more the weight of muscle adds up and the weight becomes more and hence speed would become more.
